Hi all,

I’m trying to set up load-balancing from my ViaSat satellite connection to my Android phone hotspot.
The network topology is basically as follows:

1. ViaSat modem in bridge mode connected to first WAN port of ER605 tp-link router that provides DHCP services, which is connected to my LAN.
2. TP-link router has another WAN port connected to a GL-MT1300.
3. The GL-MT1300 uses my Android phone hotspot to provide load balancing to my LAN through the tp-link router.

This seems to work okay as long as my phone hotspot is actually turned on and in range. But when it is off or out of range, the tp-link router doesn’t seem to be able to detect this. That router is supposed to be able to ping the hotspot WAN link to check if it’s up, but I can’t get that to work; the ping always fails.

If I set the hotspot link to “always on” in the tp-link router, then load-balancing works if the hotspot is available.

However, if the hotspot isn't available then the tp-link still tries to use it for load-balancing and fails, leading to connection failures.

Is there some way to make this work?

Thanks!
